Transcriptional activation assay of VaERD15 in yeast. (A) Fusion proteins of pGBKT7-GAL4 (positive control), pGBKT7-VaERD15 and pGBKT7 vector (negative control) were transformed into the yeast strain AH109. (B) Transformants were streaked onto plates of SD/Trp- and SD/Trp-/His-/Ade- + X-α-gal to detect their growth conditions and β-galactosidase activity.
